      • addPartition

        public void addPartition​(java.lang.String partitionIdStr)
        Add PartitionId to assignedPartitionIds set, if {@param partitionIdStr} valid. Used in one of the vcr state model classes OnlineOfflineHelixVcrStateModel or LeaderStandbyHelixVcrStateModel if current VCR is assigned a partition.
        Parameters:
        partitionIdStr - The partitionIdStr notified by Helix.

        Remove PartitionId from assignedPartitionIds set, if {@param partitionIdStr} valid. Used in one of the vcr state model classes OnlineOfflineHelixVcrStateModel or LeaderStandbyHelixVcrStateModel if current VCR becomes offline for a partition.
        Parameters:
        partitionIdStr - The partitionIdStr notified by Helix.
